I'm brand new to e-bikes and something just doesn't seem quite right. I just purchased a Retrospec Chatham e bike. It has 3 levels of pedal assist along with a thumb throttle and also 7 gears. It appears that the only difference in the pedal assist between Low-Med-High is that it increases my speed. I want to use my legs more and not have the "assist" help so much. But even in low (no matter what gear I'm in), it takes me up to full speed and my pedaling is basically free wheeling, there is no resistance. Is this normal or might something be wrong with my set up? Perhaps that is how the less expensive e-bikes are? I hope this makes sense. This is riding in town on flat elevation. Thank you for any input.
